Description
1/4" Stainless Steel Fender Washers | Boat Supply Store
Prevent hull damage and ensure secure mounting in demanding marine environments with these 1/4" Type 316 stainless steel fender washers. Their large diameter significantly increases the bearing surface area, reducing stress on softer materials like fiberglass or wood, critical for installations on a Bertram or a flats skiff. This Grade A4 stainless steel construction offers superior resistance to saltwater corrosion and galvanic corrosion, vital for operation in the Gulf Coast's brackish waters.
Key Features
- Distributes Load over a wider area to prevent material pull-through.
- Corrosion Resistant constructed from Type 316 stainless steel for maximum saltwater durability.
- Protects Surfaces by acting as a barrier between fasteners and deck or hull materials.
- Secure Mounting enhances the integrity of hardware installations on vessels.
- Wide Diameter provides superior load-bearing capacity compared to standard washers.
- Grade A4 Stainless offers excellent protection against crevice and pitting corrosion.
- Versatile Application suitable for numerous deck and hull hardware attachments.
- Reliable Fastening ensures components remain securely in place under vibration and stress.

Common Concerns Answered
Will these washers rust in saltwater?
Constructed from Type 316 stainless steel, these washers offer superior corrosion resistance, significantly mitigating the risk of rust even in prolonged saltwater exposure.
Are these suitable for attaching hardware to thin fiberglass?
Yes, the large outer diameter of these fender washers distributes the fastener's load across a wider surface area, effectively preventing pull-through on softer materials like thin fiberglass.
Can I use these with standard bolts?
These 1/4" fender washers are designed to fit standard 1/4" bolts and screws, providing enhanced support and surface protection for your marine fastening applications.
Frequently Asked Questions
What is the specific grade of stainless steel used?
These fender washers are manufactured from Type 316 stainless steel, also known as Grade A4, which provides superior protection against pitting and crevice corrosion.
What is the purpose of a fender washer?
A fender washer has a significantly larger outer diameter than its inner diameter. This increases the bearing surface area, reducing the stress on the material being fastened and preventing pull-through, especially in softer substrates.
How do I determine the correct size fender washer?
Select a fender washer with an inner diameter that matches your fastener's shank diameter (e.g., a 1/4" bolt requires a washer with an inner diameter around 0.265"). The outer diameter should be sufficient to adequately distribute the load for your application.
What is the recommended use for Type 316 stainless steel?
Type 316 stainless steel is highly recommended for marine environments due to its enhanced resistance to chloride ions found in saltwater and industrial chemicals, making it ideal for boat hardware.
Can these washers be used for structural integrity?
While these washers enhance the security and prevent damage from standard fastening, they are intended for load distribution and surface protection rather than providing primary structural load-bearing capacity.
